Just for your information , that the Junkboxes is to hard to get. Not even the bot seems to handle it since theres no really good place to farm these except LBRS. The CC's pick pocket the NPC's and then kills them, that means it will take a loooong time to gather 1,5k boxes.
Its meant to take a long time, if it could be done in 20minutes then it wouldnt be very insane at all
I tried farming a few of these not long ago on my rogue, for just 65 it took me just over 2 full runs of LBRS running past everything and pickpocketing. If you estimate it at ~25-28 per run that means you would need to run thru LBRS ~55 times to get 1400 boxes. You do not need to kill every mob and indeed if you leave them up then their pockets will respawn after 4minutes and you can pick some of them again on the way back out of the instance
Dont waste your time farming boxes instead offer to buy them from any rogue willing to farm them at 30g/box. That comes to a total of 42k gold which is a good selling point to any rogue you can find that is bad at earning gold for themselves.
When i farmed the insane, I kept a 10k float of gold.. anything above that 10k went into buying herbs for crafting cards. Selling the cards gave me plenty of gold in return to buy more herbs and the 10k was there for whenever any of the 5 rogues I had on payroll sent me boxes cod i could collect them asap so as to keep them working.
If you are doing the insane, then working on the presumption that you are going to be crafting decks you will have 120 trinkets to sell at between 2-4k a piece (or more depending on your server economy). The sum total output of that being between 240k-480k gold and therefore more than enough to accomodate the 42k needed to buy all your boxes.
If you get to the end of your darkmoon grind and still have boxes to farm then go ahead and farm some for yourself too but realistically you dont need to hurry the ravenholdt farm because darkmoon is going to take you some time anyway, it requires way more materials than you will ever farm yourself so your time is litterally better spent sat at the auctioneer than in the depths of LBRS. If you see bots on your AH for example, add them to friends, wait for them to come on line and snatch up all their cheap herbs when they post them
